CDO

Dear Sir,

I want to interpolate daily precipitation data on regular latlon grids to another regular latlon grids (both have same resolution 0.5 deg. x o.5 deg.). But the location of grid centers is different between the two grids.

For example in one grid description file the lat starts at 12 deg N and lon starts at 80 deg E, then in other grid descrption one grid starts at 12.5 N and lon starts at 80.5 deg E, but the increment in lat an lon are the same i.e., 0.5 deg.

Should I use conservative remapping or is it sufficient to use bilinear interpolation in CDO?

Kindly answer,
best wishes,
